  1. 21. Contested Landscapes/Contested Heritage : history and heritage in Sweden and their archaeological implications concerning the interpretation of the Norrlandian past

    Författare :David Loeffler; Lars Larsson; Umeå universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; Archaeology; Scandinavia; Sweden; Norrland; Norrbotten; Västerbotten; Lappland; Ångermanland; Medelpad; Jämtland; Härjedalen; Hälsingland; Gästrikland; history; prehistory; archaeology; philosophy; antiquarianism; heritage; cultural management; identity; Fleck; thought-collective; thought-style; colonialism; colony; periphery; hinterland; kingdom; empire; industrialism; nationalism; romanticism; Sámi; Stone Age; Mesolithic; Neolithic; semi-subterranean; dwelling; typology; C14; shoreline displacement; Arkeologi; Archaeology subjects; Arkeologiämnen; Archaeology; arkeologi;

    Sammanfattning : This case study explores how geo-political power structures influence and/or determine the conception, acceptance and maintenance of what is considered to be valid archaeological knowledge. The nature of this contingency is exemplified through an examination of how the prehistory of Norrland, a region traditionally considered and portrayed as peripheral vis-à-vis the centre-South, was interpreted and presented by Swedish archaeologists during the 20th century.

  3. 22. Road traffic metals : sources and emissions

    Författare :David Hjortenkrans; Bo Bergbäck; Per-Arne Malmqvist; Högskolan i Kalmar; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Emission patterns; Heavy metals; Roadside soil; Sweden; Traffic; Sequential extractions; SFA; Environmental chemistry; Miljökemi; Environmental Chemistry; Miljökemi;

    Sammanfattning : As the environmental regulations and technical progress have forced the factories’ old “end of pipe” solutions to improve, the metal emissions from point sources have decreased. Instead, the diffuse consumption emissions from goods in use now are in focus. LÄS MER

  4. 23. Reproductive toxicology of endocrine disruptors : effects of cadmium, phthalates and phytoestrogens on testicular steroidogenesis

    Författare :David Gunnarsson; Gunnar Selstam; Gunnar Nordberg; Per Leffler; Henrik Leffers; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Endocrine disruptors; reproductive toxicology; cadmium; phthalates; DEHP; MEHP; phytoestrogens; steroidogenesis; testosterone; Leydig cell; Molecular biology; Molekylärbiologi;

    Sammanfattning : A number of investigations during the last two decades describe adverse trends in male reproductive health, which have been proposed to be caused by environmental factors with endocrine disrupting properties. In contrast to many other toxicants, endocrine disruptors often do not show linear dose-response relationships typical of those found in traditional toxicological studies. LÄS MER

  5. 24. Ardent propaganda : miner's novels and class conflict, 1929-1939

    Författare :David Bell; Umeå universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; working-class; miners; roman à thèse; ideology; genre; context; communication;

    Sammanfattning : This study of the contribution of working-class fiction to the debate on class conflict in Britain is based on four novels written by two ex-miners between 1929 and 1939: The Gate of a Strange Field (1929) and Last Cage Down (1935), by Harold Heslop, and Cwmardy (1937) and We Live (1939), by Lewis Jones. These novels represent, in work­ing-class fiction, a unique combination of an archetypal working-class occupation, min­ing, with central features of the 1930s cultural discourse, the role of political ideology in literature.

  7. 25. Multivariate design of molecular docking experiments : An investigation of protein-ligand interactions

    Författare :David Andersson; Anna Linusson Jonsson; Gabriele Cruciani; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Molecular docking; chemometrics; multivariate analysis; principal component analysis; PCA; design of experiments; DoE; partial least-square projections to latent structures; PLS; scoring functions; ligand-binding cavity; major histocompatibility complex; MHC; glycopeptide; T-cell.; Pharmaceutical chemistry; Läkemedelskemi; datorlingvistik; computational linguistics;

    Sammanfattning : To be able to make informed descicions regarding the research of new drug molecules (ligands), it is crucial to have access to information regarding the chemical interaction between the drug and its biological target (protein). Computer-based methods have a given role in drug research today and, by using methods such as molecular docking, it is possible to investigate the way in which ligands and proteins interact. LÄS MER
